STACKER.

Specification of Letters Patent.

Patented April 14, 1908.

Application led March 26, 1907. Serial No. 364,674.

T o all whom it may concern:

Be it known that 1, CHARLIE E. LANG, citizen of the United States, residing at Erskine, in the county of Polk and State of Minnesota, have invented certain new and useful Improvements in Stackers, of which the following is a specification.

This invention relates to loading devices and more particularly to stackers for use in stacking hay and similar material on wagons or in the iield, and has for its object to provide a stacker which `will include incline tracks and a carrier movable over the tracks and in which the incline of the tracks and consequently the height to which a stack may be built, may be varied.

Another object is to provide a stacker in which the tilting of the carrier may be varied to suit different conditions.

Other objects and advantages will be apparent from the following description, and it will be understood that changes in the speciiic structure shown and described may be made within the scope of the claims, without de arting from the spirit of the invention.

n the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1. is an elevational view of the present stacker with the carrier in tilting osition, the arrangement of the tilting stops eing clearly illustrated, Fig. 2. is a view similar to Fig. 1, the carrier being shown in lowered position and the tracks being shown in raised position, Fig. 3, is an end view, Fig. 4, is a vertical section on line 4-4 of Fig. 5, Fig. 5,is a top plan. Fig. 6 is a detail section. Fig. 7 is a detail in perspective of the supplemental support.

Referring now to the drawings, the present invention comprises spaced pairs of longitudinally extending sills 6 and 7 respectively, the sills of each pair being spaced from each other in parallel relation, as shown. At their rearward ends, the sills are connected by means of a transverse member 8.

Mounted upon each pair of sills adjacent to the rearward ends thereof there is a vertical guide frame 9 including side uprights 10 secured one to each sill, and having a top member 11 secured thereupon. Each top member 11 has a vertical passage 12 formed therethrough, and slidably engaged in the passages 12 there are a pair of vertically mova le members 13 connected at their upper ends by a horizontal rod 14.

J ournaled upon the guide frames 9 at the rearward portions thereof there is a horizontal drum 15, having a gear 16 at one end meshing with a gear 17 mounted upon a stub shaft 18 carried by the adjacent guide frame 9, and the gear 17 is provided with a crank 19 by which it may be revolved to rotate the drum 15. Cables 2O are connected with the f drum 15 to be wound thereupon and are engaged with the members 13 for movement of the latter upwardly when the drum is revolved to wind the cables thereupon. Rotation of the drum in the opposite direction will allow the members 13 to move downwardly, as will be readily understood.

A pair of parallel upwardly and rearwardly inclined tracks 21 are provided, the lower end of each of these tracks being pivoted between a pair of the longitudinal sills at the forward end thereof for vertical movement of these tracks, and as shown, the tracks rest upon the members 13, the upper ends of the latter being beveled for engagement in notches 22 formed in the under faces of the track. It will thus be apparent that the members 13 may be moved to vary the slant of the tracks and means 23 is provided for holding the drum 15 with the members 13 at different points of their movement. As shown, the tracks are provided with a plurality of the notches 22.

Forwardly of the guide frames 9, there is pivoted between each pair of sills, a supplemental support 24, and the tracks 21 are provided with notches 25 in their under surfaces, for the reception of the upper ends of these supplemental supports, and the pivoting of these supports is suoli that they may be moved longitudinally. This pivoting is accomplished through Vthe medium of pins 26 engaged in the lower ends of the support and in the sills, and yokes 27 are connected with these pins and extend forwardly therefrom. Cables 28 are vconnected with the upper ends of the supports 24, and are passed beneath the yokes 27 to be connected with the track 21 above the pivot points thereof as shown. The arrangement is thus such that when the tracks are moved upwardly the cables are drawn to move the supports 24 forwardly and into engagement with lower notches 25 to aid in the support of the tracks.

A carrier 29 is mounted for movement over the tracks and consists of a shaft 30 having circumscribing grooves 31 therein which receive upwardly projecting ribs 32 formed upon the tracks, and guide rails 33 are seother.

As will be seen yfrom the drawings, the arrangement is such that when the carrier is at the lower end of the tracks, the portion 36 of the receptacle will extend horizontally to receive a load, and when the carrier has been moved to the upper end of the track, as will be subsequently described, the receptacle will move with respect to the shaft 30, to bring the portion 37 into downwardly extending position to discharge the load therefrom.

The upper ends of the tracks are rounded as shown at 38, and the shaft 30 thus moves downwardly to a slight extent over these rounded portions, thus throwing the weight of the load upon the portion 37 of the receptacle and causing the latter to move into the tilting position as just described. under the weight of the load.

A spring 39 is connected with the forward portion of the stacker and has a cable secured thereto and to the receptacle 35 of the carrier and the arrangement is such that when the receptacle is moved into tilted position, tension is placed upon the spring so that the receptacle is automatically returned to normal position when the weight of the load is removed therefrom.

A transverse bar 51 is'fixed in the upper ends of the tracks and extends outwardly therebeyond at its ends, and a pair of tilting stops 52 are journaled upon this bar 51 for vertical movement and lie in position to receive the portion 37 of the receptacle thereagainst when the carrier is dumped. By reason of the fact that the stops are movable vertically, they are arranged for adjustment v(so to vary the tilting of the receptacle, as will be readily understood.

Cables 53 are connected with the tilting stops 52 and with a transverse drum 54 which is journaled in the tracks, and which is provided with a crank 55, by means of which it may be revolved, and the arrangement is such that when the cables are wound upon the drum the stops 52 will be moved upwardly. A ratchet detent 56 is provided for the drum 54.

Mounted upon the outwardly extending ends of the bar 51 are a pair of pulleys 57, and a second pair of pulleys 58 are mounted upon the outer faces of the outermost sills 6 and 7.

Cables 59 are secured to the upper ends of the tracks and are looped around the outer end portions of the shaft 30, the latter being grooved as at 60 to receive these loops, and the cables are engaged over the pul eys 57 and thence pass downwardly and beneath the pulleys 58, beyond which they are passed forwardly through guide block 61 for mutual attachment to a draft animal, or to the winding drum of a power mechanism. It will thus be seen that when the cables are pulled forwardly the carrier will be moved upwardly over the tracks as previously mentioned.

Rollers 62 are carried by the receptacle 35 and rest upon the guide rails 33 when the carrier is moved upwardly and upon the ground when the carrier is at the downward limit of its movement.

Ihat is claimed is:

1. In a stacker, the combination with tracks of a carrier movable over the tracks, said carrier being arranged for tilting movement into discharge position at one end of the tracks, a bar extending transversely of the tracks, stops pivoted to the bar and arranged to receive portions of the carrier thereagainst to limit thel movement thereof, a drum journaled between the tracks and a cable connected with the drum and with the stops for movement of the stop when the cables are wound upon the drum.

2. In a stacker, the combination with the tracks pivoted for vertical movement, of vertical guide frames located below the tracks, supporting members mounted in the guide frames for vertical movement and arranged to receive the tracks thereupon, supplemental supports pivoted to the frames, a iiexible connection for the supplemental supports, and having one of its ends connected to the tracks and its other end connected to said supports, a drum journaled upon the guide frames and cables connected with the drum and with the first mentioned supporting members for upward movement thereof when the cables are wound upon the drum.

3. In a stacker, the combination with tracks of the carrier movable over the tracks and-including a shaft having circumscribing grooves receiving portions of the tracks, guide rails connected with tracks and lying in spaced relation thereto, said rails being engaged in the grooves and rollers carried by the carrier and arranged to rest upon the ground when the carrier is at the downward limit of its movement, and for engagement with the guide rails when the carrier is moved upwardly.

In testimony whereof I a'Hix my signature in presence of two witnesses.

CHARLIE E. LANG.
